Create Billing tab is not found in /DBM/VSEARCH transaction

Hi Experts,

I have completed doing the PGI in New vehicle sales process. Later the step is Creating outgoing invoice for customer.

I didnt find any  button in /DBM/VSEARCH transaction, for doing billing. How can i do the billing for the vehicles which i sold to the customers.

I have maintained QOIV & QFOR in action controll determination.

PFB attachment for the Vehicle order document which completed the PGI.

Thanks,

Nagaprasadreddy.
